I, to S. R. Sperans, New York, N. Y I i Application December 27, 1938,Serial .No. 247,732 q I,

I I "4 Cilaims. O urinvention relates to ,beverage dispensing apparatusand has particular reference to apv operated pump having. a. meteringcontainer in a; I

- the outside, the;-pump having valves so arranged that one completestrokeo If; the pump delivers a measured quantity oi the liquid. throughthe I "vide'a beverage dispensing .apparatus which can" paratusfordispensingbeverages and other liquids in measured quantities.

Our invention 'h as for its object to provide .a

beverage dispensing apparatus. which can be. easily and simply,operatedso asto deliver a definite quantity of" a liquid with a singlemove- I ment of a handle at the apparatus. "For this purposeweprovide-the apparatus with a hand larger vessel with a discharge pipeextending to I pipe. Wealso'provide a check valve in the discharge pipefor ipreventing the return flow of- .the. liquid and maintaining. thedischarge pipe fined; 1 I I Anotherobject of our invention is to'providethe pump assembly of the. apparatus completelymounted on the;.,co ver ofthe vesselso"'that the whole assembly can be, removed withthe coverthereby facilitating cleaning of the vessel. an of-the pump mechanism. 1

. Another obje'ctlofburinvention is, to provide an operating mechanismfor the pumppomposed' fully .01? levers. and links'without any-gearsthereby simplifying the construction and facilitating its cleaningandmaintenance. H

StiIl anotherobject of our invention isto probe conveniently supportedonthe operators body bymeans of suitable belt straps,-thevessel. be-

ing concave :at the rearsozthat it can fit the operators chest.

"Our invention is more, fully described 11'. the] accompanyingspecification and: drawings in Fig... 1 is a sectional elevation, ofour. apparatus; f Fig. 2 is a top plan view ofv the same;

Fig. 3 is a s'ectionalside view of the same;

Fig, 4 is a sectional bottom plan-view of the cover and pump plungertaken-on the line 4-4 1 of Fig. 3.

'Ourbeverage dispensing apparatus in its pre- -ferred embodimentconsists .of a vessel I having double. walls with" a space between themfilled with a-heat insulating material'2 such as rock wool, asbestos,etc. The vessel has an opening 3 on top with a short neck ,4 for a cover:5. The latter has a rubber gasket 8 for providing a tight seal betweenthe cover and the neck. The cover has extensions 1 fitting overthe-sides of the vessel and having'hooks 8 atthe ends which I of theplunger l 8.

can be engaged by clamping rings 5. The latter are supported on latchesIll pivoted at H, on brackets. l2 fastened to the sides of the vessel.By pulling the latches outward as shown in dottedlines at the left inFig. 1,:the rings9 can be released from the hooks 8 for removingthecover,

.A measuring cover by means or pipes l4 and closed at the containerl3-is supported on the bottom, .the'pipe l4 having a side opening. 16 pin communication with the bottom ofthe .ves-' sel. The upper portion ofthe pipe I5 extends above the cover .5 and is-curved inthe form of a.spout for discharging the liquid from the con+ tainer into receptaclessuch as paper cups i1.

'I'he capacity of the-container is made to correspond to the capacity ofthe cups" I]. A plunger I8 'slides "in-the container and has "a rod I9extendingto the top of the cover 5.where it has a collar 20" retainingfaspring 2| whose lower end rests against 'the bottom plate of a tube 22depending from the cover 5. i The spring therefore tends to raisethe-plunger, a stopplate 23 being provided-on the pipe [5 for limitingthe upward movement of the plunger.. "The container I3. represents atube open at the top and closed at the bottom by a'cover 24 with aflange 25 cut away to clear the :pipes Hand 15 and having angular slots26 engaging pins 21 in the container.

The cover 24. can be removedfby turning 'it sidewise until the .pinsj21enterthe straight portions of the slots so that the cover canbe pulledoff. The container can then .be washed and cleaned. The cover 24 has anopening 28 closed by a. flat plate 29 serving as 'a'valve." Hooks 30attached to the cover 24'limit the upwardmovementv of the valve 'plate'29. A supplementary valve is provided in the plunger l8 in theforrn of aflat spring 30 closing an opening 3| in the plunger at one end, theother end of the spring being attached to the plunger as'by rivets 32.

' The upper. end of the rod l9'is pivotally ;connected at 33 to one endof a link 34 whose other end is pivotally connected at 35 to the upperend ofa lever arm 36 fitted on a shaft 31. The latter is journaled inthe wall of a casing 38 supported on top of the cover 5. A handle'39 isattached to the outer end of the shaft "3! and has a lug 40 connected bya link 4| with a. the number of --st rokesv counter 42 for counting Byturning the handle 39 down, the plunger I8 is made to move downward,expelling the liquid from the container throughthe discharge pipe I5.The container and plunger-represent a pump for discharging vthe liquid.Upon release of the handle, the spring 2| raises the plunger, 7

drawing the liquid into the container from the vesselthrough the valves29 and 30. ter valve also helps to let the air escape from thecontainer. The pipe l5 has a check valve 43 for preventing the liquid inthepipefrom flowing'back into the container so that the pipe alwaysremains filled. The liquid thereforefiows from the spout of the pipe 15without any delay as soon as the handle 39 is turned. Tubular holders Mare attached to the sidesof the vessel lby straps 35 for paper.cups-which are frictionally';retained by beads' 46 abutting the againstthe operators chest. The vessel can be supported on the operators neckby belt straps 48 with a buckl'edB, the straps being attached to rings wat the top of the vessel. Similar straps 55] with a buckle 5! serve tofasten the vessel to the body of the operator, these straps extendingfrom clips 52 at the sides of the vessel.

Our dispensing apparatus has an important advantage in that it can beeasily and iquickly taken apart for cleaning. and sterilizing; the cover5 can be easilyremoved by unlatching the rings 9, the pump comprisingthe container and plunger being removed with the cover; The plunger canbe :rernoved by turning aside the stop plate so that the plunger and theinside of the container can be washed and cleaned. .The container. canbe further taken apart by removing its bottom cover it. The apparatushas also anadvantage in that it is portable and canbe carried by theoperator for delivering drinks to his customers, the quantity of liquidfor each cup'being always the same for every stroke oi the plunger. v I
